Science

Within a lead-acid battery, which consequence results when high cell temperatures limit ionic mobility?

A)Plate sulfation accelerates markedly.
B)Electrolyte concentration profile becomes uniform.
C)Self-discharge reactions minimize completely.
D)Active material conductivity improves greatly.

💡 Explanation

Accelerated plate sulfation arises because limited ionic mobility prevents complete discharge during cycling; therefore, lead sulfate accumulates excessively, rather than converting back to lead and sulfuric acid, leading to battery degradation.
